16 callback Client function for reshape-window event.
17
19 This registers a function with OpenGLUT, which OpenGLUT will invoke when‐
20 ever the window is reshaped or resized. Your callback is only invoked
21 when the host window system has actually changed the window size.
22
23 The parameters to your callback are the new width and height for your
24 window.
25
26 If you do not provide a reshape callback, OpenGLUT will simply call
27 glViewport(0,0, w, h).
28
29 This callback is bound to the current window .
30
31 To ask OpenGLUT about the present dimensions of the current window ,
32 you can use glutGet().
33
35 Unlike other callbacks, GLUT has an active default behavior if you do
36 not set this. (Most event types passively do nothing if you do not
37 specify a callback to handle them.)
38
39 The reshape callback should always be called, if registered, when your
40 window is first created.
